Question

我正在尝试使用GStreamer SDK和Android NDK在Android应用程序中显示h264编码流。我的Android.mk看起来像：

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE    := App
LOCAL_SRC_FILES := App.cpp

LOCAL_SHARED_LIBRARIES := gstreamer_android
LOCAL_LDLIBS := -llog -landroid

include $(BUILD_SHARED_LIBRARY)

ifndef GSTREAMER_ROOT
    ifndef GSTREAMER_ROOT_ANDROID
        $(error GSTREAMER_ROOT_ANDROID is not defined!)
    endif
    GSTREAMER_ROOT        := $(GSTREAMER_ROOT_ANDROID)
endif

GSTREAMER_NDK_BUILD_PATH  := $(GSTREAMER_ROOT)/share/gst-android/ndk-build/
include $(GSTREAMER_NDK_BUILD_PATH)/plugins.mk
GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_EFFECTS) $(GSTREAMER_PLUGINS_NET)
GSTREAMER_EXTRA_DEPS      := gstreamer-video-1.0
include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk

由于缺少插件 - 糟糕，我收到以下错误：

priv_gst_parse_yyparse no element "h264parse"

我的管道如下所示：

udpsrc address=192.168.0.1 port=5000 ! application/x-rtp, encoding-name=H264, payload=96 ! rtph264depay ! h264parse ! avdec_h264 ! autovideosink

那么如何将gstreamer-plugins-bad包含在android build中呢？

Answer 1

尝试添加此行而不是您拥有的那一行：

GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_CODECS_RESTRICTED)

具体来说，这个人应该完成工作$(GSTREAMER_PLUGINS_CODECS_RESTRICTED)

Answer 2

您可以添加这一行：

GSTREAMER_PLUGINS         := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) $(GSTREAMER_PLUGINS_CODECS_RESTRICTED) $(GSTREAMER_PLUGINS_EFFECTS)

在您的路径中：app/jni/Android.mk

在android中使用gstreamer插件坏了
